No, I do too, as a result of having to clean them for the REMF's in my unit who's idea of cleaning them after an FTX was running a patch down the barrel. Oh, yes, I sent them back to clean more, again and again, but I wanted to clear my stuff out, too,so I could go enjoy the cold ones I had sitting in my fridge in the barracks, just like anyone else.. I had an M35A2 I had to PMCS and clean, and an M16A1 I was issued that I had to clean, and had had the most blanks (or rounds, if after a range) through it. I'd pass still-dirty guns, then leisurely clean the whole units weapons correctly over the next week or so. So yeah, when my son son brought me the AR he was trading to me dirty, I gave him an earful, because I had trained him in how to clean it, and he had failed to do so. I will admit with my own AR's, I don't keep them to the standards expected in the Arms Room, but I do make sure the chamber, bolt, and immediate area are cleaned every time, and the rest as they get dirtier after a few outings.
